In this review, the RBC-mediated delivery of in vivo nanobiosensors for applications of bio-imaging at the single-cell level, advanced medical diagnostics, and analytical detection of biomolecules and cellular activities are presented. A comprehensive perspective of the technical framework of the state-of-the-art RBC-mediated delivery systems is explained in detail to inspire the design and implementation of advanced nanobiosensor-based theranostic platforms taking advantage of RBC-delivery modalities.

The burdens of Non-communicable Diseases have overstretched health systems in developing countries. The study explores disparities in the availability of services and predicts the readiness of primary healthcare facilities to manage diabetes in Tanzania.

The study analyzed data from the 2014-2015 Tanzania Service Provision Assessment Survey. A total of 1142 primary healthcare facilities were included in this analysis. The Negative binomial regression models were fitted to predict each of selected independent variable that is associated with the readiness of primary healthcare to manage diabetes.

The overall availability of services was significantly different across the type of facility and managing authority. In an adjusted model, the following were the predictors for a significant increase in readiness to manage diabetes health center [β = 0.470], private facilities [β = 0.252], the performance of management meetings [β = 0.446], having source of fund other than government [β = 0.193,], and presence of medical doctors [β = 0.677].

The robust primary care systems to manage diabetes could be achieved by improving the readiness of primary healthcare facilities through optimizing the availability of diagnostic tools, basic medicines, medical doctors, and early release of a government fund to publicly-owned facilities.

However, the mechanisms involved remain elusive. Reporting in Cell, Wrenn et al. describe how sealed intercellular compartments, nanolumina, are used as growth factor reservoirs within tumor cell clusters to regulate tumor cell proliferation.

A high incidence of osteonecrosis of the femoral head (ONFH), a commonly seen and intractable disease, has been reported. This retrospective study aims to compare the reconstructive outcomes by free vascularized iliac bone flap (FVIBF) with those by vascularized pedicled iliac bone flap (PIBF) to determine which one is better for ONFH patients.

From January 2010 to December 2017, 35 patients (40 hips) were treated by PIBF grafting, and 32 patients (36 hips) were treated by FVIBF grafting. The two groups were then compared in terms of the preoperative baseline conditions, intraoperative data, and postoperative Harris hip score (HHS).

In the PIBF group, the operating time was significantly longer than the FVIBF group (195.5 ± 26.4 vs 147.2 ± 17.7 min, respectively), and the intra-operative blood loss was significantly heavier (330.0 ± 63.9 vs 240.3 ± 37.5 ml, respectively). Meanwhile, the recipient site morbidity rate in the PIBF group outnumbered that in the FVIBF group (27.5% vs 8.3%, respectively), and a higher rate of lateral femoral cutaneous nerve (LFCN) injury was observed in the PIBF group than in the FVIBF group (27.5% vs 8.3%, respectively). No difference was found in postoperative HHS score between the two groups. In both groups, the recovery effect of the patients in stage II was better than that in stage III.

While maintaining a similar clinical effect, the FVIBF grafting exhibited a distinct advantage over the PIBF grafting, in terms of shorter operative time, less blood loss, and lower risk of LFCN injury.

The overnight storage of the buffy coat (BC) at room temperature has logistic and operational advantages for the blood centre. The present study aimed to evaluate the impact of an overnight hold (stored) of BC at room temperature in comparison with the 2-hour hold (fresh) of buffy coats on the platelet concentrate (PC) characteristics.

A total of 60 BCs were included in the study, 30 PCs (fresh) were prepared after two hours holding time of the BCs and the other 30 PCs (stored) were prepared after the overnight BC storage at room temperature. The primary endpoint of PCs evaluation was the platelet yield, volume, pH, WBC count, RBC count, and platelet swirling in the PC and the secondary endpoints were glucose concentration, lactate, LDH, and sterility of the PCs. All the tests were performed on the day+1 of the blood collection.

There was no difference concerning the volume, RBC count, and swirling between the two groups (P>0.05). The PCs from the fresh BC had higher pH and glucose concentration (P<0.05). On the other hand, the overnight hold of BC produced higher platelet counts, WBC counts, lactate, and LDH levels (P<0.05). All the 60 PCs did not record any bacterial growth on the culture media for the sterility results.

The overnight hold of BC produces a higher platelet yield with higher storage lesions. This may also allow better supervision, ensuring better quality control.

As part of the BSc (Hons) Diagnostic Radiography programme students learn and undertake research relevant to their development as first post radiographers (dose optimisation and image quality) within the Research-Informed Teaching experience (RiTe). Due to the COVID-19 pandemic, the delivery of RiTe to our year 2 students was moved to an online format using Microsoft Teams and Blackboard Collaborate and focused on a key area of current practice – COVID-19 and chest X-ray imaging. Within RiTe students are placed into collaborative enquiry-based learning (CEBL) groups to share tasks, but to also support and learn from one another.

An online survey was used to explore the year 2 student cohort task value and self-efficacy of this online version of RiTe.

A 73% (32/44) response rate was achieved. MM3122 Students found the online version of RiTe to be a positive learning and development experience. There was strong agreement that they not only found it relevant to their area of practice (task-value), but also strongly agreed that they understood and could master the skills taught (self-efficacy).
